Apple's software is garbage so I'm sure you're correct, but modern hard drives can do several hundred MB/s of throughput. How is that not fast enough for a freaking photo application? For Apple not to test/support this use case is inexcusable.
https://www.macobserver.com/analysis/understanding-apples-un... is an article which describes the architecture. It's not on-die, it's next to the CPU, basically as close as it could physically possibly be without being on the die.
Here's a photo of an M1 CPU:

Those chips on the right side are LPDDR4x chips (which you can verify by googling the part numbers visible on them). They are "off-the-shelf" so to speak, not custom on-die memory.
My understanding is that at least for the lower-end machines, there are no additional DRAM chips in the 8GB vs. 16GB machines, they just use chips that have double the density, so the power consumption remains the same.
Even if I'm completely wrong on the above, I seriously doubt that adding 8GB of memory to a machine that consumes 7W at idle in total[1] would add "several watts of mandatory 24x7 idle power consumption."

$200 to add 8GB of memory is _insane_, and framing it as "consumer choice" is bad when consumers are being gouged so badly. It's literally at least a 20x markup on the wholesale cost. You can buy 8GB of DDR4 at retail for $20 or less.
Usually I see that term used when the thing being considered is a pricey upgrade, and you need to strike a compromise between price and performance.
In this case, we're talking about an extra 8GB of memory, which would add perhaps $10 in cost to the bill of materials for the machine (or maybe less in sufficient volume). Given that Apple is also overcharging by at least 3x current standard retail price for SSD upgrades, my guess is that there's some room to bump up the wholesale cost a bit.
Not doing so is, IMHO, insulting to users, and given the non-upgradable nature of these machines, bad for the environment, counter to all of Apple's talk about being environmentally friendly.
You'll note that, for example, on the Macbook Air (both M1 and M2 versions), Apple labels the ports "Thunderbolt / USB 4," which is confusing and IMHO downright misleading. Either way, the reason they do that is that those ports don't support dual displays, so they only meet the Thunderbolt 3 spec, which doesn't mandate dual displays.
A better label for the Macbook Air might be just "USB 4," or "USB 4 with Thunderbolt 3 support" (though TB3 is part of the USB 4 spec, so that's technically redundant).
USB/Thunderbolt standards are fun.
